The document discusses narrative structure in trailers based on Todorov's theory of 5 stages: equilibrium, disruption, recognition, attempt to repair, reinstatement of equilibrium. It analyzes the trailer for the film "Taken," showing how it follows these stages by establishing the protagonist's daughter's birthday, her kidnapping in Paris disrupting the equilibrium, the father recognizing the disruption and vowing to find the kidnappers, and his attempts to repair the situation through fighting shown in the trailer.
